Diora S.A. – Polish electronics manufacturer with headquarters in Dzierżoniów existing throughout 1945–2006. The first polish factory to make radio recievers after World War II.

History
The factory opened its doors on the 8th of November 1945 under the name State Radio Reciever Factory in Dzierżoniów. Eventually after multiple name changes its name was changed to "Diora", an anagram of "Radio".

In 1947 licences from AGA were purchased and the production of the superheterodyne Aga reciever was started. In the meantime the company was working on developing their own cheap, mass-market design. 1948 marks the release of the first radio reciever designed fully "in house" - the "Pionier" Which ended up selling over a million units. It was kept on sale under a different name, "Promyk", until 1968. During the 50s & 60s Diora also took part in the manufacture of military radio stations and TV sets.

During the 70s & 80s Diora was part of the government-owned UNITRA electronics manufacturers association.

Starting in the late 70s Diora began offering music centres, consisting of a stereo tuner, an amplifier, a compact cassette deck and a graphic equalizer. In later years CD players were also introduced.

An important aspect of Dioras operation was the export of goods to other countries. Diora manufactured equipment for companies such as Thomson or Brandt, MacWatts, Geton, Crown Japan etc. Devices made for export were generally built with more precision and attention to detail (for ex. the export version of the WS-442 amplifier featured dials made of metal, while they were plastic in the version meant for the polish market)

In 2006 Diora was closed and buildings owned by the company were torn down.
